Does the automatic trim really work ?

Two weeks ago I have successfully updated the firmware of my brand new Intel X25 G2 80GB (to 02HA). I set the ICH9R to AHCI and then installed my brand new Windows 7 OS. I have checked that my ssd was using the MS AHCI driver. So according to Intel, everything was ok to make automatic trim work : 02HA firmware + MS ACHI driver + windows 7.

Two weeks after, all my softwares were installed on my ssd (10 GB are free now). I launched Crystal diskmark and I had only 30 MB/s for the "4k write". All the other tests ( 512 k read/write, sequential read/write and 4k read) were also a bit disappointed (but fortunately not as much as the 4k write).

So I launched the Intel SSD toolbox and ran the ssd optimizer (manual trim). And yes, after that, my ssd is like brand new : 70 MB for the 4k write... (the other values are also higher).

So, does the automatic trim really do its job ? How can I check that it is really active ?

I didnt tried it, but I just runned:

"C:\Windows\system32>fsutil behavior query disabledeletenotify"

And win replied:

DisableDeleteNotify = 0

Also crystaldiskinfo says TRIM is suported (it said it wasnt before the FW update):

I have these options in BIOS (BIOS config is correct):

-> Options under "SATA Configuration":

- DISABLE

- COMPATIBLE

- ENHANCED

If I select ENHANCED, a new field called "Configured SATA as" shows up.

-> Options under "Configured SATA as":

- IDE

- RAID

- AHCI

So i Have ENHANCED + AHCI in BIOS.

"fsutil behavior query disabledeletenotify" only tells you that Win 7 is sending the trim command. It does not tell you what, if anything, is happening to the command that it sends out. It is on by default in Win 7 so regardless if you have a trim f/w or not it will still be on unless you turn it off.

I also don't think that trim is working automatically. I've now turned off the manually scheduled trim from the toolbox and once the drive has had a chance to enter the used state I will benchmark it to find out.

Which is the setting for controller and which is for ports? And under what settings did you flash the firmware update?

Interesting, does anyone know if I can still obtain a copy of the optimization software, Intel took it off of the download site and I want it.
